如何继续此代码？ [英] How do I continue this code?

问题描述

这是一个问题：

编写一个程序，接受用户的两个整数。然后它询问用户他想用这两个数字做什么。如果用户选择是



'A' - 添加两个数字



'B' - 减去第一个数字中的第二个数字



'C' - 将第一个数字乘以第二个数字



'D' - 将第一个数字除以第二个数字



'Q' - 结束操作



你的程序应继续接受这两个数字和用户选择，除非用户输入'Q'作为选择。



这是我的代码到目前为止：

  #include    <   iostream  >  
   using   namespace  std; 
  #include   <   sstream  >  
  
 
  int  main（）
 {
  int  integar_1; 
  int  integar_2; 
  int  choice; 
  char  ch; 
 
 
 cout<<  欢迎使用基础数学计算器程序。; 
 cout<<  此程序将采用两个整数。您可以从以下5个选项中进行选择，看看会发生什么！<< ENDL; 
 
 cout<<  输入积分并按enter.\\\
; 
 cin>> integar_1; 
 cout<<  输入另一个整数并按enter.\\\
; 
 cin>> integar_2; 
 
 cout<<  您输入了<< integar_1<<  和<< integar_2<<  。<< ENDL; 
 
 cout<<  在以下字符中选择：<< ENDL; 
 cout<<   A-添加两个数字。\ n; 
 cout<<   B-从第一个数字中减去第二个数字。\ n; 
 cout<<   C-将第一个数字乘以第二个数字。\ n; 
 cout<<   D-将第一个数字除以第二个数字。\ n; 
 cout<<   Q-结束操作。\ n; 
 cin.get（ch）; 
 {
  if  
} 
 
 
  return   0 ; 
 
} 

如何继续if语句说如果用户说A，那么添加数字等？然后，如何提示用户再选择2个数字并重新执行此过程，直到他们按Q？只是一个简短的例子将有所帮助，因为我可以做其余的事情！请用C ++语言！谢谢！

解决方案

想想



（1）围绕你的主要代码循环重复直到'Q'进入 http://www.cplusplus.com/forum/general/6014/ [ ^ ]



（2）而不是使用'if'看看这个 http://www.cprogramming.com/ tutorial / lesson5.html [ ^ ]

This is the question:
Write a program which accepts two integers from the user. Then it asks the user what he wants to do with those two numbers. If the user choice is

‘A’ – Add the two numbers

‘B’ – Subtract the second number from the first number

‘C’ – Multiply the first number by the second number

‘D’ – Divide the first number by the second number

‘Q’ – End the operation

Your program should continue to accept the two numbers and the user choice unless the user enters ‘Q’ as choice.

This is my code so far:

#include <iostream> 
using namespace std;
#include <sstream>


int main()
{
	int integar_1;
	int integar_2;
	int choice;
	char ch;
	

	cout << "Welcome to a Basic Math Calculater program.";
	cout << "This program will take two integars. You can then choose from the following 5 options to see what happens!" << endl;

	cout << "Enter an integar and press enter.\n";
		cin >> integar_1;
	cout << "Enter another integar and press enter.\n";
		cin >> integar_2;

		cout << "You entered " << integar_1 << " and " << integar_2 << "." << endl;

		cout << "Choose between the following characters:" << endl;
		cout << "A- Add the two numbers.\n";
		cout << "B- Subtract the second number from the first number.\n";
		cout << "C- Multiply the first number by the second number.\n";
		cout << "D- Divide the first number by the second number.\n";
		cout << "Q- End the operation.\n";
		cin.get(ch);
		{
			if 
		}


	return 0; 

}

How do I continue with the if statement to say that If the user says A, then to add the numbers and so on? And then how do I prompt the user to pick 2 more numbers and re-do the process until they press Q? Just a short example will be helpful because I can then do the rest! In C++ language please! and thank you!

解决方案

think about

(1) a loop around your main code for repeating until 'Q' is entered http://www.cplusplus.com/forum/general/6014/[^]

(2) rather than use 'if' look at this http://www.cprogramming.com/tutorial/lesson5.html[^]
